Class IloIntExprArray

Definition file: ilconcert/iloexpression.h

The array class of IloIntExpr.

For each basic type, Concert Technology defines a corresponding array class. IloIntExprArray is the array class of the integer expressions class (IloIntExpr) for a model.

Instances of IloIntExprArray are extensible. That is, you can add more elements to such an array. References to an array change whenever an element is added to or removed from the array.

Constructor Detail

IloIntExprArray

public IloIntExprArray(IloDefaultArrayI * i=0)

This constructor creates an empty array of elements. You cannot create instances of the undocumented class IloDefaultArrayI. As an argument in this default constructor, it allows you to pass 0 (zero) as a value to an optional argument in functions and member functions that accept an array as an argument.

IloIntExprArray

public IloIntExprArray(const IloEnv env, IloInt n=0)

This constructor creates an array of n elements. Initially, the n elements are empty handles.

Method Detail

add

public void add(IloInt more, const IloIntExpr x)

This member function appends x to the invoking array multiple times. The argument more specifies how many times.

add

public void add(const IloIntExpr x)

This member function appends x to the invoking array.

add

public void add(const IloIntExprArray array)

This member function appends the elements in array to the invoking array.

endElements

public void endElements()

This member function calls IloExtractable::end for each of the elements in the invoking array. This deletes all the extractables identified by the array, leaving the handles in the array intact. This member function is the recommended way to delete the elements of an array.

operator[]

public IloIntExprArg operator[](IloIntExprArg anIntegerExpr) const

This subscripting operator returns an expression argument for use in a constraint or expression. For clarity, let's call A the invoking array. When anIntegerExpr is bound to the value i, the domain of the expression is the domain of A[i]. More generally, the domain of the expression is the union of the domains of the expressions A[i] where the i are in the domain of anIntegerExpr.

This operator is also known as an element constraint.

operator[]

public IloIntExpr operator[](IloInt i) const

This operator returns a reference to the extractable object located in the invoking array at the position specified by the index i. On const arrays, Concert Technology uses the const operator:

 IloIntExpr operator[] (IloInt i) const;

operator[]

public IloIntExpr & operator[](IloInt i)

This operator returns a reference to the extractable object located in the invoking array at the position specified by the index i.
